2x6 wood planks with bolts/screws all over surface for traction?

Or even strips of wood running sideways.

Is 6" not wide enough of a profile to provide traction?

 

I'm sure it would help but Maxtraxx are 13" wide and sometimes they feel like they're just barely wide enough for me. I have no idea if the bolts would damage your tires if you started spinning them hard. I bought a pair of the cheap traction boards off of Amazon and used them probably a dozen or so times and they're starting to wear. I would be interested in hearing what you come up with.

 

I tried something similar screwing small blocks of wood onto 2x8 boards and it didn't help, airing down the tires worked way better.
